Abstract
The terms transudate and exudate look and sound very much alike, and as both of them describe some form of oedema, they are sometimes used (wrongly) as synonyms. Their proper use is, however, of more than semantic interest because transudates and exudates arise by different mechanisms, and are therefore found in different clinical settings. Further, their compositions are different, especially with regard to protein concentrations. It is usually possible in a sample of effusion fluid collected from a serosal cavity of the body to identify it as transudate or exudate, based on its protein content; this identification is usually of great diagnostic importance.
